Protoshield Kit for Arduino


Build your own Arduino shield using the compact and flexible Proto Shield kit. Solder together a limitless range of circuits and reuse it in all your Arduino projects. A standard 0.1” prototyping grid accepts commonly used through-hole parts and chips. Basic components (resistors, potentiometer, LEDs, switches) are included to help you get started with your custom shield.


  • Arduino compatible

  • Large 0.1 inch pitch prototyping area

  • A variety of through-hole sizes to fit most parts

  • Arduino UART and I2C port pin breakouts for easy external communication interfacing

  • Dual ISP breakouts for easy programming and stacking

  • 3.3 volt, 5 volt, and ground power rails are easily available anywhere on the board

  • Breadboard style prototyping area

  • USB type B connector

  • Basic components included (buttons, switches, LEDs, resistors, USB jack)


We have produced a lot of extension board that can make your platform board more powerful, however not every extension board is compatible with all the platform board, here we use a table to illustrate how are those boards compatible with platform board.


Please note that “Not recommended” means that it might have chance to work with the platform board however requires extra work such as jump wires or rewriting the code. If you are interested in digging more, welcome to contact with

Components included in the kit

  • 1 Arduino compatible Proto Board

  • 1 B type USB connector

  • 1 40-pin 2.54mm male long header

  • 1 6-pin 2.54mm female header

  • 1 ISP female pin header

  • 1 ISP male pin header

  • 1 10k ohm potentiometer

  • 4 1k ohm resistors

  • 2 10k ohm resistors

  • 2 3mm red LEDs

Board trace schematic


Step 1: Solder the Red LED to the holes in the Power Socket outline. Be sure to match the flat side of the LED with the outline on the board. Solder the green LED to the holes in the pin13 outline on the board, again, matching the flat side of the LED to the board outline. Solder two 1K resistors to R1 and R2. Solder Reset button and ISP header per the picture below. Note: The reset button is easier to install if you insert it before inserting the ISP header.

Step 2: Solder the female and male connectors. Note: solder ADC6 and ADC7 ONLY if your are using a Seeeduino. When using an Arduino, do NOT solder ADC6 and ADC7.

Step 3: Solder the USB connector to the USB port, and the potentiometer in the 80 mil holes. Solder the bottom left Power pins to suit your project.

Your finished kit should look similar to the picture above.


Help us make it better

Thank you for choosing Seeed. A couple of months ago we initiated a project to improve our documentation system. What you are looking at now is the first edition of the new documentation system. Comparing to the old one, here is the progresses that we made:

  • Replaced the old documentation system with a new one that was developed from Mkdocs, a more widely used and cooler tool to develop documentation system.
  • Integrated the documentation system with our official website, now you can go to Bazaar and other section like Forum and Community more conveniently.
  • Reviewed and rewrote documents for hundreds of products for the system’s first edition, and will continue migrate documents from old wiki to the new one.

An easy-to-use instruction is as important as the product itself. We are expecting this new system will improve your experience when using Seeed’s products. However since this is the first edition, there are still many things need to improve, if you have any suggestions or findings, you are most welcome to submit the amended version as our contributor or give us suggestions in the survey below, Please don’t forget to leave your email address so that we can reply.

Happy hacking
